Impinj, which develops semiconductors based on RFID technology, said today that it has raised $19 million in venture capital.
AllianceBernstein, one of the world's largest asset management firms, led the round, with all previous investors also participating. They include Arch Venture Partners, GF Private Equity Group, Madrona Venture Group, Mobius Venture Capital, Polaris Venture Partners and strategic investors Unilever Technology Ventures, UPS Strategic Enterprise Fund, VentureTech Alliance and the Viterbi Group.
In total, Impinj has raised $98 million. The money will be used to escalate product development and delivery of its RFID readers, tags and antennas.
Impinj is one of the companies in town that has been named a likely candidate for an initial public offering.
